Dockge-gitops

Add gitops functionality to Dockge

Background

Switching from Portainer to Dockge I was missing the ability to have a gitops workflow. I wanted to be able to make changes to my compose.yml files and have them automatically imported to my Dockge stacks. This project is a simple temporary solution to that problem.

Features

• Clone repo into Dockge stacks directory
  • Access private repos using PAT
• Automatically poll for changes on a configurable interval
• Use global .env file to set environment variables for all stacks

Usage

Environment Variables

Variable	Description	Default	Required
REPO_URL	URL of the git repo to clone		Yes
PAT	Personal Access Token for private repos		No
POLLING_RATE	How often to poll for changes	5m	No
DOCKGE_STACKS_DIR	Path to Dockge stacks directory	/opt/stacks	No

Volumes

Host Example	Container	Description
/opt/stacks	/opt/stacks	dockge stacks dir, host must match container
/opt/env	/env	place .env file here to be copied to all stacks

Example compose.yml:

version: '3.8'

services:
  dockge-gitops:
    image: ghcr.io/ebaldebo/dockge-gitops:latest
    container_name: dockge-gitops
    restart: unless-stopped
    environment:
      - REPO_URL=https://github.com/author/example.git # required
      - PAT=ghp_iamapat123 # optional
      - POLLING_RATE=10m # optional
      # Needs to be the same as the stacks directory in the dockge container
      - DOCKGE_STACKS_DIR=/opt/stacks 
    volumes:
      # Needs to be the same as the stacks directory in the dockge container
      - /opt/stacks:/opt/stacks
      - /opt/env:/env # optional path to .env file

  dockge:
    image: louislam/dockge:1
    container_name: dockge
    restart: unless-stopped
    ports:
      - 5001:5001
    environment:
      - DOCKGE_STACKS_DIR=/opt/stacks
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data:/app/data
      - /opt/stacks:/opt/stacks

How to run

# Create directories
mkdir -p /opt/stacks /opt/dockge

# Create .env file (optional)
mkdir -p /opt/env && echo "TEST_VAR=TEST" > /opt/env/.env

# Place compose.yml in /opt/dockge
cd /opt/dockge
nano compose.yml

# Run
docker compose up -d

Update Stacks

Dockge does not automatically update stacks when changes are made, a rescan is needed. This can be done by:

1. Click your user icon in the top right
2. Click "Scan Stacks Folder"
